OVERHEAD CARRIER.

SPECIFICATION forming part of Letters Patent No. 673,270, dated April30, 1901.

Application filed January 14, 1901. serial No. 43,239. \No model.)

To all whom it may concern.-

Be it known that LSAMUEL MICHAEL J ENKS, a citizen of the United States,and a resident of Madison, in the county of Lake and State of SouthDakota, have invented a new and Improved Overhead Carrier, of which thefollowing is a full, clear, and exact description.

This invention relates to an overhead carrier adapted especially forcarrying hay and analogous loads from one place to anotherfor example,from a wagon into a barn for storage.

The carrier is adapted to be used with a sling, which may be of anydesired construction, but which is preferably of that constructiondescribed and claimed in my copending application for patent on slingsfor overhead carriers, filed January 29, 1901, Serial No. 45,190.

This specification is a specific description of one form of theinventiomwhile the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is an end elevation of the carrier with the track in section onthe line 1 1 of Fig. 3. Fig. 2 is a side view of the carrier. Fig. 3 isa longitudinal section thereof, showing the latch of the carrier lockedwith the sling; and Fig. 4 is a section showing the latch in unlockedposition.

0. represents the track on which the carrier runs. This track issuspended by hangers a and is provided at a certain predetermined pointwith a downwardly-projected stud or pin a the latter for coaction withthe carrier, as will be hereinafter explained. The detailed constructionof the track is set forth in my copending application for patent onoverhead tracks, filed January 14, 1901, Serial No. 43,240.Thecarriercomprisestwo sideframes b, which are fastened rigidly togetherby tiebolts or the like I) and which have secured between their lowerportions a casing c, having a hell or funnel shaped skirt 0 at its lowerend, this skirt projecting below the side frames 79 and having an openlower end. Wheels 5 are carried by the side frames 1) and run on thetrack a, as shown. By these means the carrier is mounted to move freelygravity attending the arm (1 along the track, the side frames 12straddling the track, as shown. Within the casing c a. latch d ismounted to rock upon a pin d, fixedly carried in the casing. The latch(1 comprises a hook d an arm d adjacent to the hook, and an arc-shapedtrack d, terminating at one end in a cavity (1 and at the other end in ashoulder (i The parts are so arranged that the latch (1 will normallyhang in the position shown in Fig. 4, which position is taken owing tothe preponderating force of In Figs. 3 and 4, e represents an eyeforming part of the sling which works with the carrier. Assuming thattheparts are in the position shown in Fig. 4, the eye 6, moving upward,will engage the arm 01 and throw the latch into the position shown inFig. 3, in which position the hook 01 is engaged in theeye e.

Acting with the latch d is a lock f, mounted in the upper part of thecasing c and arranged to rock upon a pin f, fixed in the casing c". Thislockfcomprises two arms f and f the latter having a hook-shaped end andthe two arms being spaced apart a distance approximately equal to thelength of the detent or stud a on the track. The lockfis also providedwith a roller f located at its lower portion and adapted to run on thetrack (1 of the latch d. The shoulder d of the latch strikes the rollerf and limits the movement of the latch toward the open position, (seeFig. 4,) and when the latch moves oppositely its movement is checked atthe proper time and the latch is held securely in closed position by theengagement of the roller f within the depression or cavity d in thelatch. (See Fig. 3.) Therefore when the latch moves from the positionshown in Fig. 4 to that shown in Fig. 3 the track d runs along theroller f and the lock drops into the position shown in Fig. 3, whereuponthe movement of the latch 01 will be finished. When in this adjustment,the lock f serves to prevent the return of the latch to the openposition. (Shown in Fig. 4.)

Assuming now that the parts are in the adjustment shown in Fig. 3 andthat the carrier is moving in the direction of the arrow indicated atgin Fig. 3, the hooked end of the arm f of the lock will engage with thedetent a and the lock will thereby be thrown to the position shown inFig. 4. This movement of the lock releases the latch and permits thesling, of which the eye e forms a part, to drop from the carrier. Theabovedescribed movement of the lock results, further, in the upwardmovement of the arm f o thereof, causing this arm to act with the arm f,the two embracing the detent t and securely locking the carriertherewith, preventing the carrier from moving farther on the track untilthe parts are moved from the position referred to. The carrier is thusstopped and held stationary during the descent of the sling to dischargeor receive its load, as the case may be. The look returns to theposition shown in Fig. 3, when the latch is returned to its closed orinactive position.

The carrier is provided with sheaves h, mounted on transverse pins h andarranged, respectively, at its sides, the sheaves serving to carry theropes for operating the sling and also for hauling the carrier, andthese sheaves h coact with the sheaves i, also mounted on the carrier,the sheaves 1; serving to guidethe and at the other end in a stop, and alock for the latch, the lock having a part engaging the track and.adapted to enter the depres-.

pivoted in the casing, said latch being provided with a hook, an arm andan arc-shaped 5 track terminating at one end in a shoulder and at theother end in a depression, and a pivoted lock above the latch, said lockbeing 1 provided with two arms, one having a hook- I shaped end, andwith a roller adapted to run on the" track, substantially as described.

3. The combination of a track, a stud carried thereby and projectingtherefrom, a carrier running on the track, alatch pivotally mounted in"the carrier andcomprisinga hook and an arm juxtaposed to eachother andalso comprising an arc-shaped track with a cavity or depression at oneend, and a shoulder at the other end and a look having apart engagedwith the track on the latch and capable ofentering the depression in thelatch, to hold the latch in closed position and ,to engage the shoulderto" limit the opening movement of the latch, the lock having twojuxtaposed arms' c'apable of straddling the detent on the track to holdthe carrier stationary, the dete'nt-lyin'g in the path of the arms; onthe lock;

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
